ALLA N I. J ACOBSON United States Patent 3,331,431 MULLIIUN DE'VIICE FOR WINDOW Allan ll. Jacobson, 36 Fiddlers Lane, Latham, NY. 12110 Filed June 2, 1%7, Ser. No. 643,196 2 Claims. (@l. 52-309) ABSTRACT 0F THE DISCLOSURE A removable mullion device for use with a window to convert a single pane thereof to multiple pane comprising a hollowed-out tube slidably receiving interiorly the mainbody portion of an integral in erting member of one-piece construction which comprises said mainbody portion, a piercing point, a neck and a serrated fiange. The tube is disposed in abutting relationship with the window pane and sash with sash securement effected by point engagement therewith. A longitudinal slot formed in the tube and portion complementally receives and guides said neck, and tube securement in facilitated by appropriate, manipulative movement of the serrated flange disposed on the exterior surface of said tube.

This invention relates to a removable mullion device for use with a single-pane window to convert same to multiple-pane.

Conventional mullion type windows have vertically and horizontally disposed mullions which intersect and which are permanently fixed to the sash to mount window panes or lights of rectangular or square configuration. Other mullion-type windows have diagonally disposed mullions which intersect and which are permanently fixed to the sash to mount diamond-shape window panes or lights.

In conventional mullion-type windows the dilficulty encountered has been that of the time and effort that must necessarily be devoted to periodic cleaning of the panes with their dirt-catching corners formed by the mullions, in addition to the expense entailed in the manufacture and fabrication of this type of window.

To obviate this difficulty it has been proposed to utilize interconnectable mullion elements that can be removably mounted on a single-pane window to achieve the simulation of the conventional mullion-type window. However, the proposal to utilize such interconnectable mullion elements to overcome the described diificulty and expense of the conventional mullion-type window has engendered prob ems in and of themselves.

Among these problems are the problem of the necessity that one be a skilled mechanic in order to properly install the mullion elements and their fastening means; the problem of defacement and mutilation of the windows sash by installation of the fastening means of different types to secure the mullion elements or to cooperatively secure the mullion elements; the problem of such fastening means interfering with the function of the window itself; the problem of the multitude and complexity of the fastening means along with the expense entailed thereby; the problem of the removal of the mullion elements and the reinstallation of same such as after cleaning the window pane; and the problem of the durability of the mullion elements themselves along with the loosening and rattling of same after reinstallation.

The objects of this invention are to solve the discussed problems of the art by providing a mullion device comprising a tube or mullion element and cooperative fastening means of an inserting member of simple but durable construction which the average householder can easily and readily install to convert a single-pane window to multiple-pane without defacement or mutilation of the window sash, without interference with the function of the. window; and in this connection the fastening means is of integral one-piece construction that is inexpensive to manufacture, and which has a piercing point to permit tight and snug installation of the tube with respect to the sash and window pane to inclusively afford structural rigidity and dampen windowpane vibration, and which piercing point permits removal and re-installation of the tube in a similar tight and snug manner.

These objects and other objects should be discerned and appreciated from the detailed specification taken in conjunction with the drawings, wherein like reference numerals refer to similar parts throughout the several views, in which:

FIG. 1 is a perspective view, partly in section, showing the mullion device installed in the sash of a window;

FIG. 2. is a sectional view taken along the line 22 of FIG. 1;

FIG. 3 is a view of the inserting member;

FIG. 4 is a sectional view of a modification as same would be depicted if similarly taken along the line 2--2 of FIG. 1.

In FIG. 1 of the drawings, reference numeral 1 generally refers to the invention and shows a window sash 3 with a window 'pane or light 5 mounted therewith. Tube or mullion element 7, preferably, is extruded of medium rigid polyvinyl chloride plastic to maintain inclusively the uniform shape of the tube as shown in cross-section in FIGS. 1 and 2. Tube 7 is of integral, one-piece construction and has relatively flat upper and lower surfaces 9 and 11 symmetrically disposed with respect to each other, and relatively flat top and bottom surfaces 13 and f5 symmetrically disposed with respect to each other. Surfaces 9 and 13, 13 and 11, 11 and 15, and 15 and 9 are joined by webs 17, 19, 21 and 23, respectively. A longitudinal slot 25 is formed in the end portion of upper surface 9 relative to its longitudinal axis.

Shown in FIGS. 1, 2 and 3 of the drawings is the fastening means of the inserting member 27. Inserting member 27 is of the styrene class of plastics and is formed by injection molding. Inserting member is of intergral, one-piece construction and has a main-body portion 29, piercing point 31, neck 33 and serrated flange 35. In stead of such piercing point 31, a suitable nail pin may be imbedded in the main-body portion 29. Main-body 29 has transverse wing portions 37 and 39 outwardly disposed therefrom.

FIG. 1 shows tube 7 horizontally disposed with its left end mounted by means of the cooperating inserting member 27 with the left vertical stile of sash 3. The right end of tube 7 would be similar to its left end with such right end mounted by means of another cooperating inserting member 27 with the right vertical stile.

The structure by means of which horizontally and vertically disposed tubes are interconnectingly secured to one another is deemed conventional and prior art, and hence forms no part of this invention. In this connection,

it should be mentioned that dowel pins carried by one or the other of the tubes to be horizontally or vertically disposed effect such interconnecting securement. Similarly, the description of the cooperating fastening means of the inserting member 27 with a tube 7 that is diagonally disposed would be similar.

To mount a tube 7 with respect to the sash 3 and window pane 5 with sash securement effected by the cooperative fastening means, an inserting member 27 is disposed at each end of tube 7 in opposed relationship to each other and in such manner that the inserting members 27 are slidably received interiorly of tube 7. It should be noted that in this respect the interior dimensions of the hollowed-out tube 7 are such that an interference fit is provided for the main-body portions 29 and wing portions 37 and 39 by the interior surfaces of webs 17, i9, 21 and 23, and top and bottom surfaces 13 and 15, to thereby functionally contribute to the tightness and snugness of the terminal end portions of the tube against the sash and the exterior flat, lower surface 11 against the window pane 5 to impart trength and structural rigidity to the sash and window pane, and to dampen window-pane vibration, and to thereby functionally contribute further to such tightness and snugness in the maintenance of the securement of the fastening means with respect to the sash. The longitudinal slots 25 formed in the upper surface 9 at the tube end portion complementally receive necks 33 but with similar interference fits. Interference fits are similarly provided between the lower surfaces of flanges 35 and the exterior upper surface 9. From the description it should be appreciated that to secure a tube 7 to the sash 3 by two opposed inserting members 27 is simply a manipulative function. The lower surface 11 is pressed against the window pane 5 with the householders thumbs engaging the serrated flanges 35 and thence the inserting members 27 are moved in opposite directions such that the flanges 35 will be in abutting relationship with the sash 3 to thereby imbed the piercing points in the sash 3. When the tube is thusly mounted, the flanges 35 will cover the openings of the longitudinal slot 25. The reverse of this described mounting procedure allows the removal of the tube 7 from its mounted position with respect to the sash 3.

In the modification shown in FIG. 4 of the drawings, the parts of the tube 41 and inserting member 43 are similar to the tube 7 and inserting member 27 previously described except that in each tube end portion a longitudinal slot 45 is formed in the top surface 47 and a longitudinal slot 49 is formed in the bottom surface 51. Slots 45 and 49 similarly, complementally receive the necks 53 and 55, respectively, of inserting member 43. And similar serrated flanges 57 and 59 are likewise provided. Mounting the tube 41 would be similar to the mounting of tube 7; however, with respect to tube 41 the householder would utilize the index finger and thumb of each hand to engage flanges 57 and 59.
